The displayed thummbnails appears watermarked, as do any of the images looked at using "Manage Galleries" in the ATP interface while setting up the page.

HOWEVER: Once the page is published, the watermarks do not appear. Cache has been flushed, I've tried other browsers, and I've used other machines not connected to the same network (even though no proxy is in use.)

I've read numerous posts regarding this issue going back at least three years, and attempted the solutions offered there to no avail, so I'm sure I'm not the only one having this problem.

@thlconal - I'm not seeing anything in particular out of place with your settings or your process.

I cannot say I am familiar with all of the plugins you have installed but none come immediately to mind as having any issues, have you tried checking that just in case?

If there is no plugin conflict, pleas feel free to submit a Bug Report (http://www.nextgen-gallery.com/report-bug/ ... please reference this topic) and include log in and FTP credentials to your WordPress installation with the Bug Report, too.
